Tomatoes are planted at the end of March in Southern Bulgaria in two-row strips at a distance of 100 + 40/30 cm, and on sandy soils – 70-75 / 30 cm in rows. The planted plants are watered individually with 2-3 liters of water, baits are spread. against a hog.

Thermal regime: The air temperature after planting the plants until fruiting is maintained in the range of 20-25 ° C, and when the fruits ripen it rises to 30 ° C. Temperature regulation is achieved by ventilating the greenhouse.

Water regime: During the first days, moderate soil moisture is maintained – watered with 5-10 l / m2 of water every 10-15 days. so as not to cool the soil. Later during the active growth between watering periods is reduced to 5-7 days. and the irrigation rate is increased to 10-15 l / m2, and when the fruits ripen it is watered 2-3 times a week with 20-30 l / m2.

Diet: During the vegetation the plants are fed 2-4 times with 10-15 kg / dca of ammonium nitrate. The first feeding is carried out. When the fruits of the first inflorescence reach the size of a walnut, and the last – 30 days before the last harvest.

Plant formation: Plants are formed in one stem with four or five inflorescences, as the branches (colts) are removed in the earliest phase, when they are 5 -6 cm long, and the growth peak is interrupted around May 10.

Additional pollination of flowers: To protect the flowers from falling in March, April, and in cool spring and in the first half of May, they are treated with growth preparations tomamil, uyutin, unimil, etc., in a concentration of 0.2-0 , 5% The flowers are sprayed with a sprayer in the morning 1-2 times a week. Later, the inflorescences are treated with vibrators or by moving the plants by tapping the supporting structure.
